T at whom it may concern.-

Be it known that we, PRINCE SMITH, of the firm of PRINCE SMITH & SON, inachinemaker, and SMITH AMBLER, in the employ of the same firm, draftsman, subjects of the Kingof Great Britain, residing at Burlington Shed, Keighley, in the county of York, England, have invented certain new and useful Improvements in Pressure-Applying Devices for Rolls of Combing-Machines, of which the following is a specification.

Thisinvention has reference to an improved pressure-applying device for combing-machines, and is particularly adapted for applying the :pressnre technically known as the weighting of the drawingoff rollers of combing machinery, and particularly of the type of comb known generally as the Nobles comb, as also to the drawing-off rollers.

of preparing or like inachinery,and especially those used in the working of wool.

In the drawings, Figure l is a front view of our improved method, showing the rollers partly broken away for convenience. Fig. 2 is a section on the line A B of Fig. 1. Fig. 3 isa plan view of one of the supports looking in an upward direction. Figs. 4 and 5 are a vertical and a transverse section, respectively, through the parts 9 and 10.

Referring to the drawings,in which our improvements are shown as applied to the drawing-off mechanism of a Nobles comb, the drawing-oft rollers 1 2 according to the present invention are pressed together at their opposite ends 3, 4, 5, and 6, respectively, by pairs of spiral springs 7 7, each pair of said rollers 1 and 2 being arranged one on. each end of the press-roller supports 8 9, one of which said supports, 9, in the form of a box, slides on one of a pair of the upright stands 10 10. The weighting of or pressure between the drawing-01f rollers 1 2 is adjusted by means of an adjusting-screw 11, actuated by an internally-screwed rot-ative collar 12, provided with thumb-pieces 13, a ratchet wheel or surface 14, and a pawl 18, mounted on a cross-piece 15, which cross-piece 15 carries at each of its ends a stem 16 and pin 17, which stem 16 presses on the coiled springs 7 7. The adj listing-screw 11 passes through said crosspiece 15 into the upright stand 10, and by turnin g the screwed collar 12 the distance apart of these parts is altered and the pressure upon the spring 7 is adjusted so as to regulate the pressure between the drawing-0d rollers 1 and 2. Among other advantages attained by this arrangementis that a much longer spring can be employed by bringing these weightin g-sprin gs 7 7 alongside the press-roller slide 9, and the two springs 7 7 in place ofone can be used to each slide. A much longer bearing-surface can be used, reducing thereby the liability to wear.

The ratchet 14 and pawl 18 serve to lock the screwed collar 12 in position and to prevent alteration of position of the adjusted parts.

Having now particularly described and ascertained the nature of our said invention and in what manner the same is to be performed, we declare that what we claim is 1. In a pressure-applying device for rolls of combing-machines, a pair of upright standards for supporting the upper of the rolls, a support for each end of the lower of the rolls vertically adjustable upon each of said standards, a pair of springs mounted within each of said vertically-adjustable supports, and connections between the standards and supports for vertically adjusting the latter.

2. In a pressure-applying device for rolls of combing-machines, a pair of upright standards for supporting the upper of the rolls, a support for each end of the lower of the rolls vertically adjustable upon each of the said standards, a pair of springs mounted within each of said vertically-adjustable supports, an adjusting-screw extending through each of said supports into each of said standards, a cross-piece carried by each of said screws and engaging with the springs of each of the supports to increase or decrease the tension of said springs, and means mounted upon each of said screws for adjusting them.

3. In a pressure-applying device'for rolls of combing-machines, a pairof upright standards for supporting the upper of the rolls, a support for each end of the lower of the rolls vertically adjustable upon each of the said standards, a pair of, springs mounted within each of said vertically-adj ustable supports, an adjusting-screw extending through each of said supports into each of said standards, a crosspiece carried by each of said screws and engaging with the springs of each of the supports to increase or decrease the tension of said springs, means mounted upon each of said screws for adjusting them, and means carried by the cross-head and engaging with the means for adjusting the screws for lock-- ing the latter in their adjusted positions.

4. In a device forapplying pressure to rolls of combing machinery, means for supporting the upper of the rolls, a pair of vertica11y-adjustable slidingboxes forsupporting the lower of the rolls, a pair of springs carried by each of the said boxes, and connections between the IS supports and the boxes for adjusting the boxes, thereby increasing or decreasing the tension of the springs.

In testimony whereof We have hereunto set our hands in presence of two subscribing wit- 2o nesses.
